How do I get the document ID for a Firestore document using kotlin data classes

Question

I have kotlin data class

data class Client(

    val name: String = \"\",
    val email: String = \"\",
    val phone: String =\"\") {
constructor():this(\"

I solved it by creating a extension method on QueryDocumentSnapshot like this:

inline fun QueryDocumentSnapshot.toObjectWithId(): T {
    val model = this.toObject(T::class.java)
    model.id = this.id
    return  model
}

Now I can map like this (which I find to look nice and clean):
myModelWithId = it.toObjectWithId()

For this to work I made a simple hasId interface that the model needs to implement:

interface HasId{
    var id : String
}

@IgnoreExtraProperties
data class MyModel(
        @get:Exclude override var id : String    = "",
        val data                     : String    = "",

): Serializable, HasId
